I’ve had my eye out on the Air Max 90 canvas and denim since I saw them but wasn’t sure if they were vegan or not. I shot an email to Nike and they confirmed that the canvas colorway was indeed animal free. Not 100% sure on the denim but I am assuming if they do not use leather on the swoosh or other questionable details on this particular model, it would be consistent with other non-leather uppers. Here’s what I’ve seen on various blogs and sites. I don’t know exactly where you can get these but I would just search and see what comes up. Good luck and post anything that would be useful in the comments section. Thanks!
